FIELD OF THE INVENTION

The invention relates to an electric cable for a section for a window,door or facade and a window or facade section, in particular one withsuch a cable.

DESCRIPTION OF THE RELATED ART

In the case of windows or doors with electric functional elements suchas electric-motors or electromagnetic drives, fittings, sensors, or withother consumers of electrical power, it is necessary to install a cableto the electric functional elements for power supply and/or controlpurposes.

According to the state of the art, in the case of sections, cables arerun through hollow chambers or are installed loosely along the outsideperimeter of the door or window sections. EP 0 475 417 B2 shows asolution with a cable guided through hollow chambers in buildingfacades. The reference describes a section design with a cable groovelocated on the outside perimeter of an insulation section or of anexternal section in the area of the glass recess for a form-fittingaccommodation of an electric cable. A particular disadvantage of thisdesign is the difficult accessibility in the area of the glass rebate orrecess as well as the location in a moist section of the facade, whichinvolves the danger of creeping currents and corrosion.

In addition, the known arrangements are often optically unsatisfactory.For other reasons, the known arrangements also do not meet therequirements of a modern assembly process. For example, the hollowchambers in the corner area must be closed with corner connectors—whichmay make additional machining necessary, e.g. by milling for theinstallation of the cable through the corner area. Also, additionalfunctional elements must be arranged in grooves that accommodate thecables. Thus, the cables are virtually lying in the open and unprotectedand make production more expensive. Elaborate access ways and/orconnections are required as well.

SUMMARY OF THE INVENTION

The invention provides a cable of the generic kind in such a manner thatthese problems associated with the prior art resolved, at least in part.Furthermore, a section and a window, a door or a facade element areprovided into which the cable may be integrated, requiring only minorinstallation effort.

According to one embodiment of the invention, the cable is shaped like aribbon with lateral noses (or shoulders) at its narrow sides that aredesigned to engage flexibly behind nose pieces of a cable groove on theframe section when the cable is mounted in the cable groove.

This way, the ribbon cable may be installed easily and without anycomplications and may be accommodated visually attractively in the framesection.

“Section” in the sense of this application refers, at least in part, toa multipart interlocked braced system section as well as an individualmetal section for the creation of a blind frame or sash.

The invention provides for a frame section for a window, a door or afacade element with a ribbon cable of the aforementioned kind thatfeatures a cable groove extending in the longitudinal direction of theframe section for a form-fitting accommodation of the ribbon cable.

The cable groove provides a space-saving, optically attractiveaccommodation of the ribbon cable directly on the section, in particularat one of the sections of the sash. An accommodation on the blind frameis also conceivable. However, the arrangement on the sash is preferredif power consuming and functional elements are to be located there aswell. This cable groove may be easily formed or shaped during theproduction of the section without requiring any production steps beyondthe production steps that are required traditionally for the productionof the section.

The cable groove simplifies the assembly considerably. This advantagebecomes especially clear with the utilization of the ribbon cable assuggested by the invention, which is simply clipped into the cablegroove.

It is particularly advantageous in this respect if the cable groove andthe cable are adapted to each other in such a way so that the cableconductors may be accessed from the exterior by means ofinsulation-piercing and/or insulation-cutting contacts since, in thisway, contacting occurs without the use of tools.

According to one embodiment of the invention, the cable groove is formedon the frame section within a surrounding larger groove, in particularwithin a groove adapted to accommodate fittings, and/or the cable grooveand the cable are adapted to each other in such a way that contactingthe conductors of the cable is possible from the exterior by means ofinsulation-piercing and/or insulation-cutting contacts.

The “groove within a groove” enables, in the simplest way, aspace-saving, visually attractive accommodation of a multi-conductorelectric cable directly on the frame section, in particular on one ofthe sections of the sash. An accommodation on the blind frame is alsoconceivable, however, an accommodation on the sash is preferred if thepower consuming and functional elements that are to be supplied arelocated there as well.

The cable groove may be easily formed or shaped during the production ofthe section without requiring any additional production steps beyond theproduction steps that are traditionally required for the production ofthe section.

The cable groove simplifies the installation considerably. Thisadvantage becomes especially clear with the utilization of the suggestedcables for a tool-free contacting of the conductors with the aid ofpiercing contacts. Ribbon cables are particularly well suited to thisend, which are simply clipped into the cable groove. But cables with ashape deviating from a ribbon cable geometry are conceivable as well,e.g. those with a slightly oval cross section.

In addition to the individual sections, the invention also providescomplete window, door or facade elements with such sections.

The invention relates to a facade section for a facade element and afacade element with such a facade section. This has the followingbackground. In the case of facades with electric function elements, suchas photovoltaic elements or power consumers such as illumination devicesor sensors, it is desirable to run a cable to the electric functionelements for energy supply and/or control purposes. According to thestate of the art, the cables are guided to these electrical functionelements through hollow chambers, for example. EP 0 475 417 B2 describesa cable routing through the hollow chambers. The specifications alsoshow a facade design with a cable groove arranged on the externalcircumference of an insulator or of an exterior section in the area ofthe glass recess for a form-fitting accommodation of an electric cable.A particular disadvantage of this design is the poor accessibility andtroublesome installation in the area of the glass rebate or recess. Inaddition, another disadvantage of this design lies in the placement ofthe electrical cable in a moist section of the facade, which involvesthe danger of creeping currents and corrosion. The invention solves atleast these problems.

In accordance with this design feature, a facade section is createdinitially for a facade with an undercut cable groove located on theexterior circumference of the facade section for a form-fittingaccommodation of an electric cable with at least two or more electricconductors. The facade section features at least an internal profile,preferably an insulation bridge and an external shell. The cable grooveis attached to the internal profile of the facade. Preferably, the cablegroove and the cable are adapted to each other in such a way that theconductors of the cable in the cable groove may be contacted from theexterior thereof by means of insulation-piercing and/orinsulation-cutting contacts.

In the groove, the cable can be accommodated while being protected fromany moisture, and the cable is easy to install in the groove. By thisconstruction, the disadvantages of the state of the art are remedied insimple fashion. Particular preference, for the avoidance of any moistureproblems, is given to the use of a box profile on the internal profileincluding the groove. A lateral wall of the box profile preferably isvertical to the plane of the window pane in this embodiment. Inaddition, the “groove in the groove” design enables in the simplestfashion a space-saving, visually attractive accommodation of amulti-conductor electric cable directly on the facade section, inparticular on one of the facade sections of the section. A facadesection, in the sense of the invention, is to be understood as amultipart composite section as well as an individual metal section forthe creation of a facade element. The cable groove can be easily formedor shaped during the production of the facade section without requiringany production steps in addition to those production steps that arerequired traditionally for the production of the section.

The cable groove simplifies the assembly considerably. This advantagebecomes especially clear with the utilization of the suggested cablespermitting tool-free contact with the aid of piercing contacts. Ribboncables are particularly well suited to this end since they are simplyclipped into the cable groove. But cables with a shape deviating from aribbon cable geometry are conceivable as well, e.g. those with aslightly oval cross section.

The frame section or the facade section can be made of metal, inparticular of a light metal, wood or plastic.

In addition to the individual facade sections, the invention alsoprovides complete facade elements with such sections.

Additional embodiments of the invention also may be appreciated from thedisclosure that follows and the claims appended hereto.

DETAILED DESCRIPTION OF EMBODIMENT(S) OF THE INVENTION

FIG. 1 shows a partial cross section of a window, consisting of a sash 1that is attached movably to a blind frame 2. The blind frame 2 isconnected to some brickwork or integrated in a facade.

The sections of the sash 1 or, respectively, of the blind frame 2, arein each case manufactured as composite sections and have an externalshell 3 and an internal shell 4 as well as a heat insulation zone thatconsists of insulation bridges 5 that connects the internal shell 3 withthe external shell 4.

The external shell 3 and the internal shell 4—that is, the individualsections of the composite section—are each made of metal sections andconsist, for example, of a light-metal material or of steel. It is alsoconceivable to make them of wood or plastic. For example, in warmerclimactic zones and/or in the internal refurbishing of buildings, it isalso conceivable to dispense with a composite design with an insulationbridge 5. A glass insulation pane 6 is set into the sash.

The individual sections 3, 4 of the sash 1 and of the blind frame 2 eachhave hollow chambers H as well as various grooves on their externalcircumference, in particular grooves 8, 9, to accommodate correspondingfunction elements such as fittings or drives, for example, to lock thevane on the sash 1 or to open and/or close the vane.

The fitting grooves are specially designed at the sides of the blindframe 2 and the sash 1 that face each other. A blind frame groove 7serves the form-fitting connection with adjoining construction elements(facade, additional windows, doors, etc.) or the connection to the wall.The hollow chambers H serve especially to accommodate the cornerconnectors and as heat insulation.

The section is preferably made of metal, in particular of a light metal.It may also be made of wood or plastic.

FIG. 2 shows the pane section 10 indicated in FIG. 1.

It is easy to recognize that at least one cable groove 11 is arranged onthe external circumference of the sash section, preferably extendingparallel to the section 1, for a form- and force-fitting accommodationof an electric cable 12. This cable groove 11 is arranged here at thebase of the fitting groove 9 of the sash section 1 because the ribboncable 12 is thereby arranged in a place-saving manner under fittingparts, and is invisible from the exterior. But an arrangement at anyother location of the external circumference of the section isconceivable as well.

The ribbon cable 12 (see FIGS. 3 through 5) can be easily clipped intothe cable groove 11 from outside. The cable groove 11 in groove 9extending parallel to the section at its exterior side provides theadvantage that the ribbon cable 12 lies protected and covered and doesnot disturb the view from the window, without making the installation ofthe fittings in their groove 9 more difficult and without the ribbongroove 11 hampering such installation.

It would also be conceivable to provide a corresponding cable groove 11on the blind frame (not shown here) or in another groove of the windowor in a separate groove directly on the external circumference. Thisconstruction is preferred for facades since otherwise only the glassrecess (or rebate) is available here, which is however relativelydisadvantageous due to the occurrence of moisture. But the compactarrangement of the cable groove 11 in the fitting groove 9 of theinterior shell 4 of the sash section 1 is preferred, especially in a gaparea opposite the blind frame.

Depending on the design, the sash section 1 can be used for the creationof a swivel window, a tilting window, a tilting/swivel window, a slidingwindow or, for example, glazing for a door or other structure(s) on abalcony. Alternatively, doors or facade elements can be made, with thelatter also including light roof elements, in accordance with thepresent disclosure.

The cable groove 11 for the accommodation of an electrically conductivecable will always be advantageous when the task at hand is to provideenergizeable, functional elements on the window, such as lockingelements, sensors, illuminating devices such as illuminating diodes, ora drive for opening and closing the window.

To that end, the ribbon cable 12 is run, for example, from a transitorylocation on the blind frame to the sash 1 and then guided along theexternal circumference of the sash section 1 to the functional elementsthat are to be controlled or supplied with energy, such as a drive or anelectric locking mechanism.

As illustrated in this embodiment, the ribbon cable 12 includes fourconductors and/or strands 14 arranged parallel to each other in onelayer, each of which has an insulation layer 14′ and all of which areimbedded in the casing 15 and/or base plate 16 of the ribbon cable 12,and which may be contacted in the groove from the exterior, for exampleby means of piercing contacts.

The cable casing 15 and/or the base plate 16 is provided in thisembodiment with a groove-like notch 13 between the two centralconductors 14, which notch runs parallel to the conductors 14 in theirlongitudinal direction and which provides the advantage of aligningand/or centering the ribbon cable 12 in the groove 11 by placing on thegroove 11 a corresponding plug contact that has a centering projectionthat meshes with the notch 13 (not seen here).

In the illustrated embodiment, the notch 13 has a conical cross sectionand penetrates the ribbon cable 12 almost completely (e.g. byapproximately 60-70%), which means that the ribbon cable 12 may befolded, bent and/or compressed when plugged or inserted into the cablegroove 11 until it is located in the cable groove 11 where it willexpand again to fill the groove 11. The notch 13 also serves to center,by means of a corresponding centering device (a frame element, forexample, not shown here), so that the strands 14 can be preciselycontacted.

In one embodiment, the ribbon cable 12 is elastic. In particular, thecasing 15, which forms a base plate 16, is made of a flexible material,e.g. of ethylene propylene diene monomer rubber (EPDM), in order to makeit possible to bend or run the ribbon cable 12 easily around any comerson the sash 1. In this context, the cable groove 11 may also be formedon the upper and/or lower and/or opposite section of the sash 1, i.e.completely or partially circumferential (again not seen here).

As illustrated, the ribbon cable 12 features, in exemplary fashion, fourstrand-like conductors 14. However, embodiments with more or fewerconductors 14 are conceivable as well if, for example, only one powersource is required to supply an electric drive, or if the supply of manydrives is necessary. This particular embodiment of the ribbon cable 12facilitates maintenance of a supply (or stock) of the ribbon cable 12.

The ribbon cable 12 includes lateral projections (or shoulders) thatengage elastically behind the bridges (or ridges) 22 associated with thecable groove 11, as illustrated in FIG. 3.

The shoulders or lateral projections 17, in turn, have slanted orinclined surfaces 32 at their sides pointing in the direction ofinsertion into the groove 11 that simplify the insertion of the cable 12into the cable groove 11. Additional slanted or inclined surfaces 33 onthe opposite side of the shoulders or projections 17, on the other hand,simplify the disassembly of the cable, e.g. in the case of any repairsor the like.

As may be appreciated from FIG. 3, the cable groove 11 is completelyarranged within the fitting groove 9 and has an axis of symmetry 20. Asshown, however, the cable groove 11 in the groove 9 lies slightlyshifted to one side of the groove 9, centered below the opening into thegroove 9.

In addition, both grooves 9, 11 have the same bottom and/or base 19 fromwhich lateral bridges or projections 21 for the cable groove 11 protrudeat an angle, in particular at a right angle, at least in the illustratedembodiment.

At the free end of these bridges or projections 21, the bridges orprojections 22, which are aligned with each other, form undercuts tolock the ribbon cable 12 in place within the groove 11.

The bridges or protrusions 22 are equipped with slanted or inclinedsurfaces 23 on the outside and/or towards the side of the groove openingin order to simplify the installation of the ribbon cable 12. The innerbridge surface 24 serves to reach behind the ribbon cable 12 to hold theribbon cable in the groove 11. The ribbon cable 12 fills the groove 11almost completely and closes the groove 11 with an essentially levelsurface.

The groove bridges or protrusions 22 form lateral chambers 25 and 26 inthe fitting groove 9. These chambers 25 and 26 are of different sizes,which results in an asymmetric arrangement in the fitting groove 9.Functional elements (such as electrically functional elements, asdescribed above) may be located in these chambers 25, 26.

The fitting groove 9 and/or the cable groove 11 may be formed at any ofthe typically four frame profiles or segments of the sash. The ribboncable 12 may be used in this respect in a simple manner as a supportingsurface for a fitting or for any other functional element in the groove(not shown here). The arrangement of the cable groove 11 in the fittinggroove 9 is particularly advantageous but not mandatory to practice theinvention.

The fitting groove 9 has lateral walls 27 a, 28 a as well as bridges orprotrusions 27 b, 28 b turned inward that are clearly thicker and longerthan the bridges 11 associated with the cable groove 11. The bridges orprotrusions 21, 22 of the cable groove 11 hold the ribbon cable 12 andotherwise do not have to assume a load-bearing function in thisembodiment. Accordingly, the bridges or protrusions 21, 22 may bedesigned in a material-saving manner.

Any fittings and ribbon cables 12 may be arranged in a compact way inthe clearance of the fitting groove 9 directly above the cable groove11, without the ribbon cable 12 interfering with the installation of thefittings.

The heights 29 and 30 of the bridges or protrusions associated with thegrooves 9 and 11 are selected so that the smaller height 29 is 1/3 ofthat of the larger height 30. With this ratio, the differences in theheights 29, 30 leaves sufficient space in the fitting groove 9 for anarrangement of the actual fitting parts and/or other functionalelements.

FIG. 4 illustrates an alternative design of the invention in whichadditional bridges or protrusions 31 are formed on the side of the cablegroove bridges 21 opposite the bridges 22 on which a plug element forcontacting the conductors of the cable 12 may be locked in place (notshown here). This variant is preferred if the cable groove 11 is notarranged within a fitting groove or the like. Alternatively, the lockingof the plug may occur in the fitting groove at the bridges 27, 28.

The ribbon cable 12 and the cable groove 11 are designed in such a waythat the ribbon cable 12 is safely locked in the cable groove 11 butretains at least a slight amount of lateral freedom or play within thecable groove 11. This play makes it possible to align the ribbon cable12 in the groove 11, for example, by means of a frame on which a plug isplaced, or e.g. by means of the plug itself.

FIG. 6 illustrates a post profile 101 of a facade 102 which includes aframe construction of post and bolt profiles as well as plane elementssuch as disks 103 or the like. Since the invention according to thisvariant is realizable on the post profiles as well as on the boltprofiles and is wholly or partially arranged around the framework,reference will be made in the following more generally to a facadeprofile.

Here, the facade profile 101 has an interior profile 104, an insulator105 and an exterior shell 106. Between the interior profile 104 and theexterior shell 106, sealants 107, 108 are arranged on both sides of theinsulator 105, each of which rests against one of the disks 103.

The interior profile 104 includes a box profile 109 disposed oppositelyfrom the disk 103 which encloses a hollow chamber 110.

The interior and exterior shells are, as a rule, made of metal, such asa light-weight metal including an aluminum alloy.

As illustrated, the interior profile 104 is provided with an undercutcable groove in the area of the box profile 109 for a form-fittingaccommodation of a cable, in particular of a ribbon cable 112. Here, theinterior profile is particularly advantageously formed on one of the twolateral walls 113, 114 aligned vertically to the window pane plane ofthe interior profile and/or the interior shell 104.

The exterior 106 and the interior profile 104—i.e. the individualprofiles of the composite profile—are in each case executed as metalprofiles and are made, for example, of a light-metal material or ofsteel. It is also conceivable to make them of wood or plastic. In warmerclimactic zones and/or in the interior refurbishment of buildings it isalso conceivable to dispense with a composite construction with aninsulation bridge 105.

As illustrated in FIG. 7, the cable groove 111 is formed within asurrounding groove 115 which preferably serves to accommodate functionalelements such as transformers, fitting parts or drives, e.g. to supplypower to illuminants (such as lights) or the like, as well as to attacha plug. This surrounding groove 115 also is formed on the side of theinterior profile vertical to the window pane plane, in particular on oneof the two lateral walls 113, 114 of the box profile, preferably againimmediately below the support areas for the sealants 107, 108.

According to FIG. 7, the cable groove 111 is located at the base of theadditional surrounding groove 115, which allows the ribbon cable 112 tobe arranged invisibly from the outside and, again, in a space-savingmanner. But it is also conceivable to have an arrangement at anotherlocation of the exterior circumference of the profile of the facade,although the chosen arrangement is preferred as particularlyassembly-friendly and protected from the elements.

The ribbon cable 112 simply may be clipped into the cable groove 111from the exterior of the cable groove 111.

The cable groove 111 in the groove 115 extending parallel to the facadeprofile at the latter's exterior side in accordance with FIG. 7 providesthe advantage that the ribbon cable 112 lies especially well protectedand covered and will not disturb the view, without making theinstallation more difficult.

Facade elements, in the sense of this invention, include lighted roofelements.

The cable groove 111 for the accommodation of an electrically conductingcable is always advantageous when the task at hand is to providefunctional elements such as, for example, locking elements, sensors,illuminating devices such as, for example, illuminating diodes, or adrive for opening and closing the window-containing element. In the caseof photovoltaic installations, they may also be used as an outgoingfeeder of the power that is being generated.

According to FIGS. 6 and 7, the cable groove 111 is formed into thelateral wall of the interior profile 104 in the style of an inwardrecess towards the hollow chamber 110. According to FIGS. 6 and 7, ithas, in each case, bridges or protrusions 130 abutting inward behindwhich the ribbon cable 112 may be locked in place.

According to FIG. 6, the bridges or protrusions 130 are designed to betiered into each other as a “borderline case of the groove in thegroove”, which means that they can be used to lock in a cover and/or aplug.

According to FIG. 6, the ribbon cable 112 has two and according to FIG.7, four conductors or, respectively, strands 116 that are arrangedparallel to each other in one layer, each of which has an insulation 117and is imbedded in the casing 118 or base plate of the ribbon cable 112.As noted above, the strands 116 may be contacted in the cable groove 111from the exterior, for example by means of insulation-piercing orcutting piercing contacts.

Between the two central conductors, the cable casing 118 is providedhere with a groove-like notch 119 that runs parallel to the conductors114 in their longitudinal extension and that provides the advantage ofaligning and/or centering the ribbon cable 112 in the groove 111 byplacing on the groove 111 a corresponding plug 120 that has a centeringlip 121 that engages with the notch 119.

The centering lip 121 may be designed with a spring, meaning that firstit aligns the cable 112 and then compresses the cable 112 beforeinsulation-piercing contacts touch the conductors 114.

The plug has a casing or cover 123 on which the centering lip 121 isformed. Locking projections 124 serve to lock in the cable groove and/orin the surrounding groove (FIG. 7).

A lateral casing lip 125 may extend into the area of the glassinstallation seals that, for example, are penetrated vertically by acable on the plug in order to connect sensors or photovoltaic elementsor the like, for example in the glass rebate (or recess), with theribbon cable 112.

The notch 119 preferably has a conical cross section and penetrates theribbon cable 112 almost completely (e.g. by approximately 60-70%), whichmeans that it can be bent and/or compressed when inserted into the cablegroove 111 until it is located in the cable groove where it will expand.The notch 119 also serves to center, by means of a correspondingcentering device (frames, not shown here), to allow the strands 116 tobe precisely contacted.

The ribbon cable 112 is elastic in this embodiment. In particular, thecasing is made of a flexible material, for example of EPDM, to make itpossible to easily bend and/or place the ribbon cable 112, as discussedabove. In this respect, the cable groove 111 may also be designedcompletely or partially circumferential (again not shown here).

The ribbon cable 12 illustrated in FIG. 2, for example, exemplarilyincludes four strand-like conductors 14. But models with more or fewerconductors 14 also are conceivable, if, for example, only one powersupply is required to supply an electric drive. This ribbon cable 12makes stock keeping very simple, as discussed above.

The ribbon cable 112 has lateral projections or shoulders that engageelastically behind bridges or protrusions 130 of adjacent and protrudinginwardly into the cable groove 111.

According to FIG. 7, the plug can be locked onto inwardly protrudingbridges 128 of the surrounding groove 115. A centering frame may beassigned to the single or multiple-part plug to align the cable 112,which frame is initially locked onto the groove and which aligns thecable 112 before the plug contacts the cable 112 (not shown here). Theplug may also be clamped or screwed into the profile for anchoringpurposes.

In addition, both grooves 111, 115 have one and the same bottom and/orbase 119 from which the lateral marginal bridges or protrusions 127 ofthe cable groove 111 protrude at an angle, in particular at a rightangle. At the free ends of these bridges or protrusions 127, the bridgesor protrusions 130 face one another and form the undercuttings for thelocking of the ribbon cable 112 and/or of the plug 120.

The ribbon 112 fills the groove 111 almost completely and closes it withan essentially level surface.

In the areas in which no plugs are placed on the cable grooves 111 orthe grooves 115, the latter can be closed with preferably pluggablecoverings (not shown here).

According to FIGS. 6 and 7, bridges or protrusions directed at eachother are thus formed at the free ends of the marginal bridges orprotrusions of the cable groove 111 that form an undercutting for atleast the cable 112. Preferably, the bridges or protrusions 130 areformed in steps and form an undercutting for the cable 112 and a plug120 that may be locked onto the cable groove 111 from a positionexterior to the groove 111. The cable 112, in turn, is preferably formedas a ribbon cable with several conductors 116 preferably arrangedparallel to each other in one layer. Here, it has again more than two,preferably four conductors and/or strands 114 arranged parallel to eachother in one layer that are imbedded in the casing 118 of the ribboncable 112. In addition, the cable 112 is disposed in a direction lateralto the locking projections 124. The casing 118 in turn is provided witha groove-like notch 119 which has a conical cross section and whichpenetrates the cable by more than 50%, preferably almost completely.

In this respect, the plug 120 with insulation piercing contacts isattachable to the facade profile, and, in particular, is lockable on thecable groove 11 or the surrounding groove. The plug can be designed inone or several pieces, and a centering frame may be assigned to it. Itis also conceivable that the plug may be clasped or screwed into thefacade profile, and/or that a centering lip 121 is formed on the plug toengage in the notch 119 of the cable.
